| - 2 - Apparently the idea is that when the pressed metal dash is attached by screws solidly to the body frame, the whole body and chassis assembly is increased in torsional stiffness. On these cars flapping of the radiator from side to side does not occur even when the axle is shimmying, and it may have a considerable effect in preventing shimmy. Is it not possible that with rubber suspension at the rear of the engine the bearer tubes might be attached rigidly at the front end to the radiator cross-member and an effect of "cushioned" torsional rigidity produced which would give freedom from tramping or shimmy without roughness in riding or increase in the sensation of engine roughness within the car?
